Some of the tricks employed by this demonically swift n speedy gamer to achieve the new record:

Breaking his own legs to gain speed. This works by saving and quickloading just before crippling your character; if done correctly the game grants you a 152% speedboost.

Playing the game in Italian, as it is quicker than the English voice acting.

Skipping NPC dialogue via quicksaves.

Clipping through walls using quicksaves—Kungkobra notes that “wall collision is kinda dodgy in this game.”

Freezing enemies. As Kungkobra explains it, if you bring up the map screen and then place a custom marker fast enough, the process will halt enemies around you. This is how he blazes past difficult enemies—the speedrun is a lot of literal running through the wasteland.
